The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252.Mar 17, 2020
The formula for this approach is: horsepower = RPM (multiplied by) torque (divide by) 5,252. If the RPM of any vehicle motor is 5,600 RPM and torque is 350 foot-pounds, then all you need to put the values in the formula to calculate horsepower of the engine. (5,600 × 350) ÷ 5,252 = 373.19 HP.
The quickest method to closely estimate motor horsepower is to use a digital clamp meter to measure current and voltage to the motor, and then perform a simple calculation. Use this formula to estimate motor horsepower. Horsepower(hp)= Voltage x Amperage x % EFF x power factor x 1.73/746.
Calculate the horsepower or CC by multiplying or dividing by 15. The general rule is for every 15 CC there is 1 HP. For example, for a 150 CC engine you would take 150 divided by 15, which equals 10 HP.
horsepower, the common unit of power; i.e., the rate at which work is done. In the British Imperial System, one horsepower equals 33,000 foot-pounds of work per minute—that is, the power necessary to lift a total mass of 33,000 pounds one foot in one minute.

Example #1: How Much HP Is 200 cc? Hence, a 200cc or 0.2L small, four-cycle engine has a horsepower of about 6.21.
For this example, the engine size is found to be 750CC’s. Next, use the formula above to convert this value to horsepower. HP = CC/ 15 = 750 / 15 = 50 horsepower.
The larger the engine, such as those in a performance car, the faster you can go from zero to 60 mph. All these factors determine what the horsepower of modern vehicles needs to be to operate efficiently and effectively. Right between 200 and 300 is a good amount of horsepower for a car.
James Watt, who invented steam engines, figured out a mathematical way to equate horses to engine power. … Thus the term horsepower was invented. Watt measured the capability of a big horse to pull a load and found it could pull a weight of 150-pounds while walking at 2.5 miles per hour.
For the average sedan, horsepower between 200 and 300 will offer much more potential under the gas pedal. … Right between 200 and 300 horsepower is the sweet spot for many drivers. Be cautious with models that approach 300 horsepower, unless the vehicle is a heavy truck or another large model.
Meanwhile, power is up 10 horses for the standard 2021 Charger Hellcat, to 717 horsepower. Component upgrades include a 2.7-liter supercharger (up from 2.4 liters), 14.5 psi of boost pressure (versus 11.6 psi in the standard Hellcat), a 300-rpm redline raise to 6,500 rpm, and two dual-stage fuel pumps, up from one.Jul 2, 2020

The Koenigsegg Gemera is the world’s quickest production car that hits the 0-60 mph mark within 1.9 seconds. It’s the very first four-seater by Koenigsegg and the world’s first Mega-GT that weighs 4,079 pounds.
turbocharged 3.0-liter six-cylinder with 382 horsepower and 368 pound-feet of torque (M340i) turbocharged 2.0-liter four-cylinder and an electric motor with up to a combined 288 horsepower and 310 pound-feet of torque (330e)
The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252. You can use our horsepower calculator below to try it out yourself.
This complex system of electric motors, gas engine and turbocharger comes together to produce more than 1000 horsepower. Mercedes-AMG reports this extreme supercar will reach 124 mph (200 km/h) in less than 6 seconds and reach a top speed of 217 mph.
To translate, a car that needs 200 horsepower to overcome aerodynamic drag at 150 miles per hour, would need 1,600 horsepower, or eight times as much, to reach 300 miles per hour. But to build a 300-mile-per-hour car, it’s not as simple as a monstrous engine.
Power is equal to work divided by time. In this example, P = 9000 J /60 s = 150 W . You can also use our power calculator to find work – simply insert the values of power and time.
Since one electric horsepower is equal to 746 watts, the formula to find watts is to multiply electric horsepower by 746.
Converting BTU to Horsepower
To convert BTU per hour to horsepower use the following equation: Power (Horsepower) = Power (BTU per hour) x 2,545.
6.5 HP (212cc) OHV Horizontal Shaft Gas Engine, EPA.
A rule of thumb for small, 4-cycle, utility engines is 32.5cc per horsepower. By this formula a 10 hp engine would have a displacement of 325cc.
Power and Torque
The Honda 160cc lawnmower engine has a maximum speed of 3,300 rpm and can output 7.1 to 8.4 foot pounds of torque, depending on the exact configuration. Most 160cc Honda mower engines output around 5.5 horsepower.
